Software Interface Specification for HiRISE Reduced Data Record ...

ISIS components applicable to HiRISE include radiometric calibration, map
projection transformation, image mosaicking, camera pointing correction, and
general image enhancement, display, and analysis tools. For more information
on this freely available image analysis package, see the ISIS web site
(http://isis.astrogeology.usgs.gov/).
HiROC’s pipeline processing starts when the WatchDog procedure, responsible
for periodically monitoring the RSDS, determines a raw science data file is ready
to be downloaded from the RSDS and passes the name of the product to the
HiDog pipeline (Downlink Organizer). The HiDog pipeline retrieves the data
product then submits the file name to the EDRgen pipeline (EDR generator) for
creating the EDR product and populating the EDR product table with metadata
about the product. The EDR_Stats pipeline creates an ISIS file and generates
image statistics that are placed in the EDR products table. The HiCal pipeline
performs the radiometric correction (see Section 4.1.1), and generates a browse
and thumbnail image of the EDR product to be used by the HiRISE and PDS
Imaging Node data-distribution web services. When the HiCal pipeline
determines two channel files of a CCD have been calibrated the file names are
passed on to the HiStitch pipeline for creating an intermediate CCD image file.
